TIRE;

the rim of a vehicle'wheel, a plurality of radially mounted helical springs and inclosing the same in a detachable shoe or casing.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had, to the accompanying drawings forming a part hereof, in which Figure 1 isa side elevational view partly in section and partly in side elevation of a vehicle wheel equipped with my improved tire. Fig. 2 is an enlarged detail sectional view of a portion of my improved tire. Fig. 3 is a cross sectional View taken on the line 3-3 of Fig. 2. Fig. 4 is a detail sectional view of one of the bearing plates or sheaths, and Fig. 5 is a detail perspective view of one of the spring retaining brackets.

My improved tire is designed to be used on an ordinary v'elncle wheel and consists of a detachable shoe or casing 1 secured to the rim 2 by means of any suitable well-known form of clencher device. As illustrated in Fig. 3 of the drawings I have shown a clencher device comprising a rim provided with the usual 'inturned edges 3, one of which has a locking ring 4: secured thereto by means of a bolt 5, in order to engage the edges of the tire when secured in position.

Secured to the inner face of the rim 2 by means of bolts'6, is a plurality of inverted U-shaped brackets 7 for securing to the rim of the wheel, the inner ends of a plurality of radially disposed helical springs 8. The

Specification of Letters Patent.

Application filed March 18, 1913.

And to this end the invention resides in connecting to Patented May 5, 1914.

Serial No. 755,218.

inner convolutions of these springs are passed around under the brackets 7 and are radially disposed thereon, and flaring cups 9 secured by the rivets 10 to the" upper face of the brackets are provided for retaining the springs in their proper alined positions on the brackets and for also preventing their lateral movement when thetire is in use. The springs have their outer convolutions provided with sheaths or bearing plates 11 which are preferably formed of thin sheet metal and are sprung over the outer convolution'of the spring as shown on the drawings and are provided for protecting that portion of the shoe or casing with which the springs contact.

By referring to will be noted that I have provided the shoe or casing with a series of inwardly projecting ribs 12 arranged in spaced relationon the inner face thereof and between which are fitted the brackets 7 for preventing the angular displacement of the springs at their outer ends when the tire is in use.

It is obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing-from the spirit of'my invention and therefore I do not wish to be limited to such features except as may be required by the claim.

What is claimed as new is In combination With a wheel rim, a casing secured thereto, brackets mounted upon the rim and having intermediate portions spaced from the rim, conical members mounted upon the intermediate portions of the brackets, and cone-shaped coiled springs interposed between the brackets and the casing, the smaller convolutions of the springs snugly receiving the conical members and the innermost convolutions of the springs engaging between the intermediate portions of the brackets and the rim.

In testimony whereof I afiix my signature in presence of two witnesses. I

CHARLES GAUL.
